ENVIRONMENTAL ISSUES
The issues for (1) ____________ economies are a little more straightforward. The desire to build on
undeveloped land is not (2) ____________ out of desperation or necessity, but is a result of the relentless
march of progress. Cheap labour and a relatively highly-skilled workforce make these countries highly
competitive and there is a flood of inward investment, particularly from (3) ____________ looking to take
2
advantage of the low wages before the cost and standard of living begin to rise. It is factors such as these that
are making many Asian economies extremely attractive when viewed as investment opportunities at the
moment. Similarly, in Africa, the relative (4) ____________ of precious metals and natural resources tends to
attract a lot of (5) ____________ companies and a whole sub-industry develops around and is completely
dependent on this foreign-direct investment. It is understandable that countries that are the focus of this sort of
attention can lose sight of the environmental implications of large-scale industrial development, and this can
have devastating consequences for the natural world. And it is a (6) ____________ cycle because the more
industrially active a nation becomes, the greater the demand for and harvesting of natural resources. For some,
the environmental issues, though they can hardly be ignored, are viewed as a (7) ____________ concern.
Indeed, having an environmental conscience or taking environmental matters into consideration when it comes
to decisions on whether or not to build rubber-tree ( 8) ____________ or grow biofuel crops would be quite (9)
____________ indeed. For those involved in such schemes it is a pretty black-and-white issue. And, for vast
(10) ____________ of land in Latin America, for example, it is clear that the welfare of the rainforests matters
little to local government when vast sums of money can be made from cultivating the land.

Passage A: (5 PTS)
COMMUNICATING WITH THE FUTURE
In the 1980s the United States Department of Energy was looking for suitable sites to bury radioactive
waste material generated by its nuclear energy programs. The government was considering burying the
dangerous wastes in deep underground chambers in remote desert areas. The problem, however, was that
nuclear waste remains highly radioactive for thousands of years. The commission entrusted with tackling the
problem of waste disposal was aware that the dangers posed by radioactive emissions must be communicated to
our descendants of at least 10,000 years hence. So the task became one of finding a way to tell future societies
about the risk posed by these deadly deposits.
Of course, human society in the distant future may be well aware of the hazards of radiation.
Technological advances may one day provide the solutions to this dilemma. But the belief in constant
technological advancement is based on our perceptions of advances made throughout history and prehistory.
We cannot be sure that society won’t have slipped backward into an age of barbarism due to any of several
catastrophic events, whether the result of nature such as the onset of a new ice age or perhaps mankind’s failure
to solve the scourges of war and pollution. In the event of global catastrophe, it is quite possible that humans of
the distant future will be on the far side of a broken link of communication and technological understanding.
The problem then becomes how to inform our descendants that they must avoid areas of potential
radioactive seepage given that they may not understand any currently existing language and may have no
historical or cultural memory. So, any message indicated to future reception and decipherment must be as
universally understandable as
possible.
It was soon realized by the specialists assigned the task of devising the communication system that
material in which the message was written might not physically endure the great lengths of time demanded. The
second law of thermodynamics shows that all material disintegrates over time. Even computers that might carry
the
message cannot be expected to endure long enough. Besides, electricity supplies might not be available in 300
generations. Other media storage methods were considered and rejected for similar reasons.
The task force under the linguist Thomas Sebeok finally agreed that no foolproof way would be found to
send a message across so many generations and have it survive physically and be decipherable by a people with
few cultural similarities to us. Given this restriction, Sebeok suggested the only possible solution was the
formation of a committee of guardians of knowledge. Its task would be to dedicate itself to maintaining and
passing the knowledge of the whereabouts and dangers of the nuclear waste deposits. This socalled atomic
priesthood would be entrusted with keeping knowledge of this tradition alive through millennia and developing
the tradition into a kind of mythical taboo forbidding people to tamper in a way with the nuclear waste sites.
Only the initiated atomic priesthood of experts would have the scientific knowledge to fully understand the
danger. Those outside the priesthood would be kept away by a combination of rituals and legends designed to
warn off intruders.
This proposal has been criticized because of the possibility of a break in continuity of the original
message. Furthermore, there is no guarantee that any warning or sanction passed on for millennia would be
obeyed, nor that it could survive with its original meaning intact. To counterbalance this possibility, Sebeok’s
group proposed a “relay system” in which information is passed on over relatively short periods of time, just
three generations ahead. The message then to be renewed and redesigned if necessary for the following three
4
generations and so on over the required time span. In this way information could be relayed into the future and
avoid the possibility of physical degradation.
A second defect is more difficult to dismiss, however. This is the problem of social exclusiveness brought
about through possession of vital knowledge. Critics point out that the atomic priesthood could use its secret
knowledge to control those who are scientifically ignorant. The establishment of such an association of insiders
holding
powerful knowledge not available except in mythic form to nonmembers would be a dangerous precedent for
future social developments.

Passage B: (5 PTS)

ENERGY FROM THE WAVES
The quest for sustainable sources of energy has led humans to study the energy potential of the sun and
the wind, as well as the immense power created by dammed rivers. The oceans, too, represent an impressive
source of potential energy. For example, it has been estimated that the oceans could provide nearly 3,000 times
the energy generated by hydroelectric dams such as the Hoover Dam. Yet, this source remains quite difficult to
exploit.
But this challenge has not prevented scientists from trying. Within the last few decades, several
technologies that can transform the ocean’s immense forces into usable electricity have been invented and
introduced. Some focus on capturing the power of the changing tides, while others rely on thermal energy
created by oceans in certain tropical regions. However, the most common and easiest-to-develop technologies
are those designed to harness the power inherent in the ocean’s waves.
There are several methods by which ocean-wave energy can be collected. All of them work because the
movement of the water that the waves induce creates storable energy by directly or indirectly driving a power
generator. In one such technology, the changing water levels in the ocean that are produced by waves lift a long
floating tube comprised of many sections connected by hinges. As the sections move up and down with the
water, they pump a special fluid through the tube that can be used to drive a generator. Another technique
works on a similar principle, only the floating object rocks back and forth with the motion of the water instead
of up and down. A third method of collecting wave energy relies on the rising water from the waves to
compress air in a partially submerged chamber. As the waves rush into the chamber, they push the air out
through a narrow tunnel. Located inside this tunnel is a turbine connected to a power generator. The movement
of the air turns the turbine, which feeds energy into the generator.

The drawback to each of these concepts is that they make it necessary to have many pieces of machinery
linked together. This presents a problem because the larger the device, the more vulnerable it is to damage
from hazardous ocean environments, and the more likely it is to interfere with otherwise unspoiled coastal
scenery. Also, these methods demand the construction of site- specific machines that take into consideration
average local wave heights and sea conditions. In other words, the ability to get power from waves differs from
region to region.
Japan, Norway, and the UK have all attempted to generate energy by capturing the power of ocean waves.
In northern Scotland, the first power plant to use wave power, OSPREY (Ocean Swell Powered Renewable
Energy), began operating in 1995. It followed the principle of the third method described above: waves entering
a partially submerged chamber pushed air into turbines ; to generate electricity. The electricity was then
transmitted to power collectors on the shore via underwater cables. Unfortunately, the OSPREY plant was
destroyed in a large storm, highlighting an unavoidable difficulty associated with this kind of power generation.
The potential benefits of wave-based energy are hard to ignore. Once the proper machinery is produced
and installed, the energy is free. Maintenance costs are small, and the equipment does not pose any threats of
environmental pollution. And best of all, the amounts of energy produced are enormous.
However, these theoretical advantages have yet to be fully realized. In many cases, a lack of government
funding has inhibited the technologies from advancing. For example, despite the relative abundance of
proposed wave-power devices, many have not been adequately tested, and most have been evaluated only in
artificial pools where they are not subjected to the harsh marine conditions that exist in actual oceans.
Protecting the equipment from the sea’s destructive forces, as well as the fundamental task of determining
feasible locations for collecting energy, also present formidable challenges. All in all, while ocean power offers
some intriguing possibilities, the difficulties involved in harnessing this energy source are substantial and will
require more time to overcome.

Passage C: (10 PTS)
For many environmentalists, the world seems to be getting worse. They have developed a hit-list of our main
fears: that natural resources are running out; that the population is ever growing, leaving less and less to eat;
that species are becoming extinct in vast numbers, and that the planet's air and water are becoming ever more
polluted.
But a quick look at the facts shows a different picture. First, energy and other natural resources have become
more abundant,. not less so, .since the book 'The limits to Growth' was published in 1972 by a group of
scientists. Second, more food is now produced per head of the world's population than at any time in history.
Fewer people are starving. Third, although species are. indeed becoming extinct, only about 0.7% of them are
6
expelled to disappear in the next SO years, not 25-50%, as has so often been predicted. And finally, most forms
of environmental pollution either appear to have been exaggerated, or are transient - associated with the early
phases of industrialisation and therefore best cured not by restricting economic growth, but by accelerating it.
One form of pollution - the release of greenhouse gases that causes global warming - does appear to be a
phenomenon that is going to extend well into our future, but its total impact is unlikely to pose a devastating
problem. A bigger problem may well turn out to be an inappropriate response to it.
Yet opinion polls suggest that many people nurture the belief that environmental standards are declining and
four factors seem to cause this disjunction between perception and reality.
One is the lopsidedness built into scientific research. Scientific funding goes mainly to areas with many
problems. That may be wise policy but it will also create an impression that many more potential problems
exist than is the case.
Secondly, environmental groups need to be noticed by the mass media. They also need to keep the money
rolling in. Understandably, perhaps, they sometimes overstate their arguments. In 1997, for example, the World
Wide Fund for Nature issued a press release entitled: 'Two thirds of the world's forests lost forever'. The truth
turns out to be nearer 20%.
Though these groups are run overwhelmingly by selfless folk, they nevertheless share many of the
characteristics of other lobby groups. That would matter less if people applied the same degree of scepticism to
environmental lobbying as they do to lobby groups in other fields. A trade organisation arguing for, say, weaker
pollution control is instantly seen as self-interested. Yet a green organisation opposing such a weakening is seen
as altruistic, even if an impartial view of the controls in question might suggest they are doing more harm than
good.
A third source of confusion is the attitude of the media. People are dearly more curious about bad news than
good. Newspapers and broadcasters are there to provide what the public wants: That, however, can lead to
significant distortions of perception. An example was America's encounter with EI Nino in 1997 and 1998. This
climatic phenomenon was accused of wrecking. tourism, causing allergies, melting the ski-slopes, and causing
22 deaths. However, according to an article in the Bulletin of the American Meteorological Society, the damage
it did was estimated at US$4 billion but the benefits amounted to some US$19 billion. These came from higher
winter temperatures (which saved an estimated 850 lives, reduced heating costs and diminished spring floods
caused by meltwaters).
The fourth factor is poor individual. perception. People worry that the endless rise in the amount of stuff
everyone throws away will cause the world to run out of places to dispose of waste. Yet, even if America's trash
output continues to rise as it has done in the past, and even if the American population doubles by 2100, all the
rubbish America produces through the entire 21st century will still take up only one-12,000th of the area v of
the entire United States.
So what of global warming? As we know, carbon dioxide emissions are causing the planet to warm. The best
estimates are that the temperatures will rise by 2-3°C in this century, causing considerable problems, at a total
cost of US$5,000 billion.
Despite the intuition that something drastic needs to be done about such a costly problem, economic analyses
dearly show it will be far more expensive to cut carbon dioxide emissions radically than to pay the costs of
adaptation to the increased temperatures. A model by one of the main authors of the United Nations Climate
Change Panel shows how an expected temperature increase of 2.1 degrees in 2100 would only be diminished to
7
an increase of 1.9 degrees. Or to put it another way, the temperature increase that the planet would have
experienced in 2094 would be postponed to 2100.
So this does not prevent global warming, but merely buys the world six years. Yet the cost of reducing carbon
dioxide emissions, for the United States alone, will be higher than the cost of solving the world's single, most
pressing health problem: providing universal access to clean drinking water and sanitation. Such measures
would avoid 2 million deaths every year, and prevent half a billion people from becoming seriously ill.
It is crucial that we look at the facts if we want to make the best f: possible decisions for the future. It may be
costly to be overly optimistic - but more costly still to be too pessimistic.

of all endangered animal species live in the world's rainforests. The destruction of the forests effectively
represents a
complete removal of all these plants and animals. Deprived of their natural environments, they will disappear
altogether. Again, this process is reversible. Man, no matter how powerful he considers himself, does not have
the power to establish the species he is so willfully destroying.
